Really! The 72's were still on order when my car was being built so we went with 52's. I have got to stay off these boards! Everytime I get off here, I learn something new and want to spend more money on my car! Too bad I can't work on the dam thing myself...

Every time the car ramped up to 350 hp it would take a dive. That's what the v shapes are on the chart. the meter would hit 4.7 volts. full load the dme can measure.

I still have it. Still waiting for the right price or I'll just keep it. It's a great car.

Jimbo, The MAF should measure way past 4.7V, the DME caps at around 5V.. Not telling you what to do, but there is something else (other than MAF maxing out) that is going on...

With the new software, we are able to run 83# injectors on a 944NA with factory like idle...

I will be ordering some 72lb injectors for now. I will see where they take me. If things don't workout with the new hardware. I will contact you. Thanks

FOR SALE 52 lb injectors less than 500 miles of use on them. These were purchased for $400 I will take best offer.

You should get some Delphi or Siemens 72lb's from racetronix for around $210.

Racetronix doesn't sell the good siemens 2.8 ohm injectors. I don't want to use resisters.

Does 0.45 of an ohm change your mind on the use of resistors?

I think the resisters look getto. One more thing that can go wrong. It's just preference. I'll spend a little more on the higher ohm injectors for that clean stock appearance.

I have run siemems 55lb injectors for 1 1/2 years and they work well. I would have to agree that racetronix doesent sell the top of the line...if you want the best buy it. I have been satisfied with mine.
